Ilmenite is an important metallic ore, and its advantages include the following:

1. Widely used: The main component of ilmenite is titanium, which has relatively stable chemical properties and is therefore widely used in aviation, aerospace, chemical, construction and other fields.

2. Low mining difficulty: Compared to deep-water or underground mines, ilmenite has lower mining difficulty and saves mining costs.

3. Environmental protection: Compared to the excavation and extraction of other metals, the collection and processing of ilmenite have a much smaller impact on the environment. Moreover, in the context of technological progress and sustainable development, ilmenite will also have stricter control over its environmental impact.

4. Stable market demand: Ilmenite is widely used in the industrial sector, especially in high-tech fields such as aerospace, where demand is relatively stable.

In summary, the widespread application of ilmenite, low mining costs, environmental friendliness, and stable market demand all make it an important metal ore.
